Allergic bronchopulmonary aspergillosis
Abstract:
Allergic bronchopulmonary aspergillosis, a syndrome associated with asthma, manifests with transient pulmonary infiltrates and eosinophilia and can progress to severe proximal bronchiectasis, bronchocentric granulomatosis and pulmonary fibrosis. Early recognition and treatment should favorably influence these complications. Use of the precipitins test with Aspergillus antigens as a screening procedure has identified 99 possible cases in California over a 50-month period. At least 44 cases have been confirmed; and demographic analysis shows that a preponderance of them involved patients less than 35 years old, occurred in farming and rural communities and were discovered in the months of September through February.
Insights
Allergic bronchopulmonary aspergillosis (ABPA) is linked to asthma and can cause lung damage. Early detection using Aspergillus precipitins tests identified many cases, particularly in young adults in rural areas during fall and winter.
Area of Science:
- Pulmonology
- Infectious Diseases
- Allergy Immunology
Background:
- Allergic bronchopulmonary aspergillosis (ABPA) is an inflammatory lung disease associated with asthma.
- It can lead to irreversible lung damage, including bronchiectasis and fibrosis, if not treated promptly.
Purpose of the Study:
- To assess the utility of the precipitins test for screening potential cases of ABPA in California.
- To analyze the demographic and seasonal patterns of confirmed ABPA cases.
Main Methods:
- A retrospective analysis of screening results using the precipitins test against Aspergillus antigens.
- Demographic and temporal data collection for confirmed ABPA cases identified over a 50-month period.
Main Results:
- The precipitins test identified 99 potential ABPA cases, with 44 confirmed.
- Confirmed cases predominantly affected individuals under 35 years old.
- Cases were more common in farming and rural communities and diagnosed between September and February.
Conclusions:
- The precipitins test is a valuable screening tool for identifying potential ABPA cases.
- ABPA appears to disproportionately affect younger individuals in rural settings, with a seasonal peak in diagnosis during autumn and winter.
